A year on from when I first interviewed the Avalon Community Energy (ACE) group, they’ve made some great progress. Their proposal for a local renewable energy park now has a site, which will have an anaerobic digester, and this weekend they launched their share offer so local people can now invest in the project. Starting with solar panels, the group will be gradually expanding and installing different renewable technologies and food production so that they compliment each other and form a resilient and diverse range of energy generation for the local area.
As part of the future plans for ACE, the group is considering aquaponics so I joined Maddy from ACE on a tour of bioaqua farm, where co-founder Antonio was generous enough to share his time and advice with us. I asked Antonio about the difference in nutrient content between hydroponics (plants in a water based system) and aquaponics where the plant nutrients in the water system come from fish which are farmed on the site.
Sometimes you ask and you find, other times you just have to relax and let things happen. As rain started the aptly named George and Pilgrim pub sheltered me, where by chance I met the amazing Earl at the bar. He’s been a long time member of the Green Party and has started a local energy cooperative called Avalon Community Energy (ACE Ltd). When I heard that I laughed and said “Wonderful! I’ve been looking for you all day, do you want to sit down?”
Despite a long term disability, Earl has been working with others in his community to bring about a renewable energy park. The plan which they are currently seeking funding for is to combine a number of energy generating aspects that support each other. An anaerobic digestor (converting biological waste into gas), a wind turbine, solar panels and aquaponics (cultivating fish). The beauty of the system is that the different aspects support each other. A modern battery that we are all familiar with is made of acids and toxic chemicals, but a battery is really anything that will store energy. The approach ACE want to take is to use the wind turbine to pump water into a raised reservoir to store the energy. The water an then be released through a turbine when energy is needed. The fish tanks generate nutrients from the fish poo which then flows to feed a hydroponics (growing plants in water) area. Solar panels will be on the roofs of the chicken sheds, who’s waste will feed the anaerobic digestor. It may all sound a little complicated, but then if you tried to describe a foodchain it might sound a little complicated too. In natural systems one ‘waste’ becomes something else’s food, and it is these principles that ACE is trying to emulate.
The group was fortunate to be able to seek out local expertise in finance, energy and organising. There is a lot of support available at the moment for community groups who want to set up an energy cooperative, so if you are interested in the idea find a local energy cooperative to advise you and check out the Center for Sustainable Energy.
